Geological Setting |
Lithology: Granite and gneiss of the Willyama supergroup. Tectonics: Syn- to post-tectonic granitoids intrude the Willyama metasedimentary and meta-igneous rocks that were complexly deformed and metamorphosed (to amphibolite facies) during the 1600Ma Olarian Orogeny. Further folded and deformed in Palaeozoic orogeny. Alteration: albitisation Hostrock Age: Mesoproterozoic, 1579±2 Ma age from a sodic granitoid at Crocker Well | ||
Age of Mineralization |
Mineralisation took place in fractures and breccias as the granite cooled hence the mineralisation age should be about the same as the granite (1575-1580Ma?). | ||
Mineralization |
Ore Mineralogy: Disseminated davidite mineralisation in a matrix of biotite, albitic feldspar and apatite. Mineralization Description: Uranium mineralisation is localised along a system of south-dipping fracture zones in foliated migmatitic granite and gneiss. Ore Controls: structural (fracture zones) | ||
MetallogenicAspects |
Granitoid intrusions widespread. Granitoids (~1590Ma) are contemporaneous with high grade regional metamorphism and deformation and with Hiltaba suite granitoids and associated Olympic Dam mineralisation. | ||
Age of Mineralization |
